I plan on a submerged pitot (anti-ice old glider style) that will sit just above my nose light. I have a nifty pressure tester that couples with an iphone app. The tester is the blue phone size rectangle in the pics and I used my ipad for the controls.

I really need to test as close to 180 knots as I can but maybe 40 or 50 will tell the story. I’m thinking can I angle the pitot without changing its pressure collection much at all?

Certainly a regular pitot would be an issue as such a small opening would soon have its lip covering the ‘relative wind’. What about a 1″ tube that collects the pressure before it gets to a submerged pitot getting the pressure off the back wall of the tube.

Interesting…. So I build a wind tunnel using my domestic fan in about an hour only to discover it makes around 6 knots of wind. Not enough!

Plan B is to stick my hand out of a moving car window for the test. Anybody need a used cardboard and pipe wind tunnel?
